在2项实验中，家养大鼠品系（Sprague-Dawley; N= 48）的优势群体雄性对引入殖民地的同种陌生人的攻击包括全方位的威胁表现和实际的咬人攻击。这些占主导地位的男性攻击和咬麻醉和未麻醉的陌生人，但威胁显示和咬伤麻醉大鼠是有限的。这些咬伤造成的损伤是非随机分布的，大多数损伤在头部和上背部，很少有咬伤在腹侧表面。当引入的陌生人留在殖民地几天后，66%的人被杀死，这表明驯化的老鼠能够在没有外部刺激的情况下对同种进行致命攻击。（PsycINFO数据库记录（c）2016阿帕，保留所有权利）
In 2 experiments, attacks by dominant colony males of a domesticated rat strain (Sprague-Dawley; N= 48) on conspecific strangers introduced into the colony included both a full range of threat displays and actual biting attack. These dominant males attacked and bit both anesthetized and unanesthetized strangers, but threat displays and bites to anesthetized rats were limited. Lesions resulting from these bites were nonrandomly distributed, with most damage to the head and upper back and very few bites to ventral surfaces. When introduced strangers were left in the colonies for several days, 66% were killed, indicating that domesticated rats are capable of lethal attacks on conspecifics without external provocation.(PsycINFO Database Record (c) 2016 APA, all rights reserved)
